A calm, classic sudoku with nothing in the way.
• No ads, ever. No purchases, no account.
• No mistake limit — play at your own pace.
• Every puzzle has exactly one solution, so you never have to guess.
• Four levels: Easy, Medium, Hard, Expert.
• Pencil notes that tidy themselves, undo, and a hint when you're stuck.
• Mistake checking is optional — off by default for the full challenge.
• Works offline. Your games never leave your iPhone.
